Description Gordon Jin 2010-01-03 17:50:17 UTC
GLSL spec 4.1.7 says "Samplers are not allowed to be operands in expressions".

But piglit/tests/glslparsertest/shaders/dataType19.frag uses sampler in constructor expression, and it gets passed in current mesa:

uniform sampler1D s;
void main()
    int i = int(s); // conversion not allowed

Fixed with glsl2 merge.

verified with mesa master d442a01ac14382d83cdaac87d2832315ceb3e963.
